L2 證據顯示 2020–2022 三篇較新整合分析一致指出鋅作為抗憂鬱藥輔助治療可顯著改善症狀（SMD -0.36，治療反應不佳者 Hedges' g -0.67 至 -1.0），且憂鬱症患者血清鋅普遍偏低，效應方向一致、機轉合理，超出 C 級的「不一致小型試驗」門檻。
但僅作為輔助療法（非單獨療法）有效、樣本量整體仍偏中等、且患者衛教機構（Mayo/Cleveland/Harvard/NIMH/APA）全數未將鋅列入推薦清單，故未達 A 級的「強證據+權威背書」。
綜合判定為 B 級（中等證據，輔助用途下效益真實但需謹慎）。

Zinc supplementation combined with antidepressant drugs for treatment of patients with depression: a systematic review and meta-analysis
結論：Zinc reduced depressive symptoms versus placebo (SMD -0.36, 95% CI -0.67 to -0.04), with a larger effect in those aged 40+ (SMD -0.61, 95% CI -1.12 to -0.09).
前往 PubMed Zinc as an adjunct to antidepressant medication: a meta-analysis with subgroup analysis for different levels of treatment response to antidepressants
結論：Adjunctive zinc lowered HDRS scores versus placebo at 6 weeks (Hedges' g = -0.67, p = 0.03) and 12 weeks (Hedges' g = -1.0, p = 0.03), with stronger effects in the treatment-resistant subgroup.
前往 PubMed Zinc in depression: From development to treatment: A comparative/ dose response meta-analysis of observational studies and randomized controlled trials
結論：Highest vs lowest zinc intake was associated with 28% lower depression risk (RR 0.66, 95% CI 0.50-0.82), and zinc monotherapy lowered symptom scores (WMD -4.15 points, 95% CI -6.56 to -1.75, p<0.01).
前往 PubMed The efficacy of zinc supplementation in depression: systematic review of randomised controlled trials
結論：Zinc significantly lowered depressive symptom scores when used as an adjunct to antidepressants, but evidence for zinc alone in non-depressed/healthy subjects was unclear (qualitative synthesis; no pooled estimate due to heterogeneity).
前往 PubMed Zinc in depression: a meta-analysis
結論：Depressed subjects had lower blood zinc than controls (difference -1.85 µmol/L, 95% CI -2.51 to -1.19, p<0.00001), with greater severity linked to lower zinc; this is an association of zinc status, not evidence that supplementation treats depression.

People who have low levels of zinc seem to benefit most from zinc supplements. Zinc supplements are used to prevent or treat zinc deficiency. Don't use a zinc supplement that's placed into the nose, called intranasal zinc. This form of zinc has been linked to loss of the sense of smell. 來源↗

The FDA has not approved any natural products for treating depression. Although research is ongoing and findings are inconsistent, some people report that natural products, including vitamin D and the herbal dietary supplement St. John's wort, helped their depression symptoms. However, these products can come with risks, including, in some cases, interactions with prescription medications. 來源↗

台灣 PTT、Dcard、Mobile01 社群討論鋅的主軸集中在男性保健、壯陽、提神、免疫與掉髮，少數心得提到「補鋅後精神比較好、比較不疲倦」，但極少把鋅直接連結到憂鬱症治療；偶有貼文引用研究指鋅與情緒、壓力反應有關，整體屬於輔助保健語氣，並非主動推薦給憂鬱症患者。
💬社群實感
意見分歧
破解迷思 社群最常見的 5 個誤解
✓
事實以為吃鋅就能直接「抗憂鬱」或取代身心科藥物
✓
事實把「補鋅後精神變好」等同於改善憂鬱情緒，混淆疲勞與憂鬱
✓
事實認為劑量越高越有效，忽略 35 mg/日上限與長期高劑量會缺銅
✓
事實誤以為睡前吃鋅能助眠抗焦慮，但部分人反而精神變差睡不著
✓
事實把含鋅綜合維他命（如克補+鋅）當成情緒保健品而忽略其他成分交互作用
